Abstract
A device to control machines by voice is disclosed which responds to a plurality of predetermined musical tones in a sequence to generate a digital control output signal. Audio conversion means convert the sequence of tones into a corresponding sequence of digital number signals which are temporarily stored in a memory. Then a sequence of ratio signals are generated by dividing each of the digital number signals by one of the digital number signals. The resulting sequence of ratio signals is then converted into a corresponding sequence of digital numbers which comprises the digital control output signal. A microprocessor and associated storage processes the digital data and controls the conversion of the musical tones into corresponding digital numbers.
